Gold Variegated Japanese Sedge
A plant with the magical Midas touch, Carex oshimensis 'Evergold' shines brightly wherever you put it.
The words 'must-have' are often over-used when describing plants but they're probably justified here. Quite simply, this is one of those plants that you'll wonder how you ever gardened without. First off, it's rather handsome, with narrow yellow leaves edged smartly in green - the colouring reminiscent of vintage railway signage on close inspection. The proportion of yellow to green is rather high, but that doesn't mean it's a weak or spindly plant, far from it. Growing happily in sun or shade in a range of sites and soils, it's as tough as anything. Particularly effective in winter gardens where its evergreen leaves combine beautifully with the coloured bark of dogwoods, willows and the like.
Stunning and versatile, brings light to dull corner and makes an excellent plant for front gardens.

Although this is an undemanding plant, it pays to give it a bit of attention at the start so you get the best results for the minimum of effort. Pick a site in sun or partial shade (it will grow in full shade, but the colour will be slightly greener and growth will be slower). Dig over the planting site and if the soil is poor, very dry or stony, add some well-rotted manure or compost. Soak the roots before planting by submerging the pot in a bucket of water for a few minutes. Then plant into your prepared soil and water in well, 'puddling' water around the plant so the soil settles around the roots.
Water well in the first season to get the roots established - once the plants have rooted well into the surrounding soil, no more watering will be necessary, except in severe droughts.
Feeding isn't strictly necessary in most soils, but if after a year or so your plants look like they could do with perking up, apply a balanced general purpose feed like Bonemeal or Growmore in spring as the plants come into growth.
Pruning is easy - simply comb through the plants with your fingers in late winter to remove any dead leaves.
